Adolescent delinquency and academic underachievement are both linked with child and adolescent behavior problems. However, little is known about behavioral pathways leading to these adverse outcomes. Children's aggression, opposition, status violations, and property violations scores were collected at ages 5, 10, and 18. Delinquency and academic…

Background: Recent studies suggest that the association between maternal age at childbearing (MAC) and children's disruptive behaviors is the result of family factors that are confounded with both variables, rather than a casual effect of environmental factors specifically related to MAC. These studies, however, relied on restricted samples and…

Background: Previous research has identified that staff-client interactions play an important role in the origin and maintenance of challenging behaviour. Particularly, the reciprocity between staff behaviour and client behaviour has been considered a key issue. Furthermore, severe challenging behaviour has been found to elicit negative emotional…

We investigated the relationship of discrepancies between VIQ and NVIQ (IQ split) to autism symptoms and adaptive behavior in a sample of high-functioning (mean FSIQ = 98.5) school-age children with autism spectrum disorders divided into three groups: discrepantly high VIQ (n = 18); discrepantly high NVIQ (n = 24); and equivalent VIQ and NVIQ (n =…

Disruptions to hypothalamic-pituitary-adrenal (HPA) axis function have been associated with varying forms of psychopathology in children. Studies suggesting children with ADHD have blunted HPA function have been complicated by the prevalence of comorbid diagnoses and heterogeneity of ADHD. The goals of this research were to assess the relations…

This study explored correlations between risk factors and eating behavior problems in late adolescent, non-clinical females (N = 301). Participants completed questionnaires for assessing eating problems, the closely associated factors of Body Mass Index (BMI) and body dissatisfaction, and a number of other risk variables that are thought to be…

Although the quality of parenting predicts externalizing behavior problems generally, ineffective parenting may be less relevant to explaining the behavior problems of children high in callous-unemotional traits. This study tested the potential moderating role of psychopathic features among juvenile offenders (n = 76). Youths were administered the…

Background: Antisocial behaviour is often comorbid with depressed mood but is itself a collection of heterogeneous behaviours. Using a genetically informative design, we examine heterogeneity in antisocial behaviour and overlaps between different forms of antisocial behaviour with depressed mood. Methods: Data were drawn from the G1219 large-scale…

We designed this study to assess parental, behavioral, and psychological factors associated with tobacco use among Chinese adolescents. The data were collected from 995 middle school students in Nanjing, China. Both smoking experimentation and current smoking (smoking in the past 30 days) were assessed among the study sample. Psychosocial measures…

Parenting stress may be inevitable for any parent. However, stress can be even greater for parents with children who have disabilities. Among parents of children with disabilities, parents of children with autism are particularly at risk of feeling overwhelmed due to the specific developmental condition and characteristics of children who have…

Errors in written multi-digit computation were investigated in children with math difficulties. Third- and fourth-grade children (n = 291) with coexisting math and reading difficulties, math difficulties, reading difficulties, or no learning difficulties were compared. A second analysis compared those with severe math learning difficulties, low…

Background: Aggression is a common type of problem behaviour in clients with mild to borderline intellectual disability who live in a residential facility. We explored contextual events that elicit aggressive behaviour and variables that were associated with such events. Method: Respondents were 87 direct-care staff members of 87 clients with…

This study examined teachers' reports of early teacher-child relationships by focusing on their assessments of the severity and the causes of children's social behaviors. Eighty-one kindergarten teachers filled out questionnaires about socially inhibited, hyperactive, and average children (n = 237) selected from their own classes. Multilevel…

The first aim of the present study was to examine associations between different aspects of adolescent friendship relations (i.e., frequency of contact with friends, trust in friends, and perceived friends' deviance) on one hand, and adolescent problem behavior and self-esteem on the other hand. The second aim was to determine whether the findings…

Background: Psychopathology in youth appears to be linked to deficits in regulating affective responses to stressful situations. In children, high-quality parental support facilitates affect regulation. However, in adolescence, the role of parent-child interaction in the regulation of affect is unclear. This study examined physiological reactivity…
